Germanium Hazard : a great boost-OD !

Here is the prototype of my boost-OD based on 2 germanium transistors AC128

It generates crunch and distorsion by itself, but also (thanks to its huge output voltage level, set by the volume pot) can overdrive the input of the amplifier following the pedal (if you choose to do so).

Please note that it can help to overdrive the following pedal or solid state amps as well, or (with “normal” volume set) send a moderate signal level to the following equipment.
